Referring now to FIGS. 4 and 5, the present embodiment of the inventionincludes a power supply subsystem for converting standard household110/220 Volt alternating current into direct current and supplying it tofirst connector 38 as +24 Volt direct current. When control switch 50 isclosed, a power supply converts alternating current power into directcurrent power at voltage levels required for HARRIS 117 radio 24, i.e.,+24 Volt direct current, and outputs the converted power to firstconnector 38 to allow for powering of HARRIS 117 radio 24 when installedor docked onto adapter assembly 10. A suitable power supply is anADA600F power supply manufactured by Cosel U.S.A. Inc located in SanJose, Calif.

Audio amplifier circuit is design with a five watt audio amplifier ICLM384N manufactured by National Semiconductor. Audio amplifier circuitacts as a power amplifier and relay for electrical signals generated bythe HARRIS 117 radio handset when connected via microphone adapters 54,55. In this manner, communications exchanged through the handset can beheard via speaker and the volume amplifier circuit provides a powerboost of 34 db maximum and operates off the +24 Volt input supply. Theoutput is frequency limited by a low pass output filter. The outputlevel is controlled via 20 k ohm resistor mounted on the front of theunit.

Inasmuch as power supply conversions and power switch wiring arewell-known in the electrical arts, further discussion as to theelectrical characteristics and properties of the internal power suppliesfor converting standard 110/220 volt AC into direct current will not bediscussed as they are not necessary for a complete understanding of theinvention herein described.

An adapter line connects the input/output of the HARRIS 117 radio 24handset line to the adaptor assembly 10 and internal microphoneelectronic, and line connects radio handset with the adaptor assembly 10to allow the transmission of voice communications (i.e. audio signals)to and from the handset. Additional electrical communications alsooccurs with the HARRIS 117 radio 24 via connectors 38 and 44 Thecombination of the HARRIS 117 radio 24, and the adaptor 10 allow theHARRIS 117 radio 24 to operate while allowing others in the vicinity ofthe adaptor unit 10 to hear incoming and outgoing voice transmissions.The LS/671 Speaker connector located on the back of the unit isconnected into this circuitry. This allows the LS/671 it broadcast theaudio from the handset plugged into the front of the unit as well as thecommunications received into the radio. The speaker on the front of thebase station will also broadcast the audio signals from the Handsetplugged into the LS/671 External SINCGARS Speaker.

An alternative embodiment of the present invention is shown in FIGS. 6and 7. This embodiment includes an assembly 80 that includes the abilityto switch between AC power and DC power (20 v-30 v) seamlessly andautomatically in the powering of tactical radios. This capability allowsfor the assembly 80 to be connected to both the AC grid and standardtactical batteries currently available throughout the military or tostandard military DC vehicle power. Should the AC grid fail the unitautomatically will switch over to the DC power without interruption ofthe power provided to the radio, power amplifiers, external speakers,etc. This switchover is fully automatic and requires no action by theoperator.

FIG. 7 shows a rear view of the assembly 80 of this embodiment. Theassembly 80 includes an AC Power (85-260 VAC) Connector 82 and two DCPower (18-32 VDC) Connectors 84. The DC Connectors 84 allow forindependent batteries (including vehicle batteries) to be attached tomaintain radio power. This embodiment also provides two LS/671 speakerconnections 86 in addition to two TOCNET control ports 88. Thisembodiment of the assembly weighs approximately 20 pounds and has sizedimensions of 13″×13.5″×17.5″. While the embodiment shown is configuredto hold up to two SINCGARS RT-1523 model radios, other embodiments couldbe configured to hold other models of radios including: PRC-117; PRC-150and PSC-5.

The assembly 80 in this embodiment may also provide a DC power outputconnector 90 using the standard power connector found in militaryvehicles. This output connector 90 can provide power for communicationsaccessories such as the ITT Tactical Data Router (TDR) and FCBC2 (ForceXXI Battle Command, Brigade and Below) Devices to operate on theassembly's power grid. Additionally, a global positioning system (GPS)unit may be connected (connector not shown) to and powered by theassembly 80.

In an alternative embodiment shown in FIG. 8, the assembly 80 is sealedwith gaskets from the exterior environment. The seal prevents dust andwater from getting into the internal compartments of the assembly 80. Inthis embodiment, the cooling fans along with their respective vent holesin the rear of the assembly 80 are removed. Instead, the assembly usesinternal heat sinks (not shown) to provided cooling for the internalcomponents. Additionally, the entire housing is sealed with gaskets thatmeet military specification (MILSPEC) standards. The gasket sealprevents electromagnetic interference (EMI) discharge.

Another embodiment of the present invention includes a Vehicle AdapterAmplifier (“VAA”) provides range extension and allows for rapid radiodismount capability. The SINCGARS VAA Vehicular Radio Mount AM-7239 isdeployed into many vehicles and includes the interface for two SINCGARSRT-1523 Radios, one Remote Power Amplifier AM-7238 with an electricalconnector, and an Internet Controller (INC) which is required forDigital Communications. The electrical connector for the Remote PowerAmplifier is adapted and arranged for supplying power from at least twoof the power supplies to the Radio Frequency Power Amplifier (“RFPA”)AM-7238 and a speaker supported by the base.

In this embodiment shown in FIG. 9, the top side 22 of the mount isadapted to simultaneously support the vehicular radio mount AM-7239 andthe radio frequency power amplifier adjacent to one another. A connectoris found on the left side of the front of the unit to provide theinterface for the Radio Frequency Power Amplifier AM-7238. To that end,top side 22 includes a substantially flat, horizontal first platform forsupporting the vehicular radio mount AM-7239 and a lower substantiallyflat horizontal second platform for supporting RFPA along with a higher,substantially flat, horizontal third platform for supporting a circularconnector 92 to provide the ability of the unit to accommodate a LS/671SINCGARS External Speaker with Microphone/Handset.

The backside of the mount includes an interface connector for digitalcontrol of the Radio Frequency Power Amplifier AM-7238 and a 28 VDCpower out connector. Backside further includes slot access holes (asshown in FIG. 7) to allow a flow of air through base as generated by afan mounted in the bottom access panel of the unit.

In this alternative embodiment of the invention, the power supplysubsystem converts standard household 110/220 Volt alternating currentinto direct current and supplies it to first connector as +28 Voltdirect current and to second connector as +28 Volt current. When controlswitch is closed, a first power supply converts alternating currentpower into direct current power at voltage levels required for SINCGARSRT-1523 radio, i.e., +28 Volt direct current, and outputs the convertedpower to first connector to allow for powering of SINCGARS VAA VehicularRadio Mount AM-7239 when installed or docked onto adapter assembly. Asuitable power supply for first power supply is a ADA-750 power supply

A second power supply is provided for converting direct current powerinto direct current power for powering RFPA. Thus, when control switchis closed, second power supply converts 28 Volt direct current into +13Volts direct current, +200 Volts direct current and +6.75 Volts directcurrent, which is directed to the second connector for powering RFPA. Aportion of the +13 Volts direct current is used to supply power to anaudio amplifier circuit.

The input/output of the SINCGARS RT-1523 radio voice communications areall accessed through a “Boat” connector. These signals are used toprovide the input for the internal speaker, the Active Net LED and theLS-671 connectors on the top of the unit. The LS/671 Speaker connectorlocated on the top of the unit is connected into this circuitry. Thisallows the LS/671 it broadcast the audio from the handset plugged intothe front of the unit as well as the communications received into theradio. The speaker on the front of the base station will also broadcastthe audio signals from the Handset plugged into the LS/671 ExternalSINCGARS Speaker. Under normal radio operations the LS/671 ExternalSpeaker requires the Radio to be placed in a remote mode for operations.As this unit is primarily for fixed site operations where the externalspeaker is used to monitor radio communications in a commander's officethis interface does not require the radio to be placed in Remoteoperation mode but allows the handset to be operated at the radio andthe LS/671 Speaker and Handset. This embodiment also includes two lightemitting diodes which indicates when a given radio is active to enablethe radio operator to identify which radio is in operation when multipleradios are installed in one location.

The placement of the power amplifier minimizes the overall footprint ofthe unit while staggering the placement of the second power supply topromote cooling of the power amplifier mounted in the VAA by insuringthe exposure of the power amplifier's cooling fins to the air.
